Hi Matteo,
I probably should have left this one for Paolo but he has been very busy lately :)
System-Defined Locales
Cisco Unified CME provides internal localization support for 12 languages including English and 16 countries including the United States. User locales specify the language to use for text displays; network locales specify country-specific tones and cadences. View the list of system-defined locales and their two-letter codes by typing ? after the user-locale and network-locale commands in telephony-service configuration mode.
For the Cisco Unified IP Phone 7912, 7940, and 7960, the system-defined user locales and network locales are preloaded into Cisco IOS software.
For the Cisco Unified IP Phone 7911, 7941, 7961, 7970, and 7971, you must download locale files to support the system-defined locales and store the files in slot 0, flash memory, or on an external TFTP server.
